RAZOR Filed sept. 7. 1935 Patented Apr. 13, 1937 UNITED vSTATES PATENT orties 16 Claims.

This invention relates generally to razors and specifically to safety razors, an object being to provide a razor having a plurality of cutting edges and means whereby the said edges may be selectively brought into operative position.

A further object is to provide a razor having ahead with a plurality of cutting edges and means whereby the head may be adjusted relatively to the handle so as to bring a desired pair of cutting edges into operative position.

A still further object resides in a razor having a headand handle so associated that the cutting edges of the razor may be brought into a plane parallel to the handle to permit of the device being used, if desired, as a straight razor.

A still further object includes a razor whose cutting edges have a guard so arranged as to permit of adjustment of the same relative to the cutting edges.

With these objects in view, together with others which will appear as the description proceeds, the

` invention consists in the novel construction, combination and arrangement of parts, all as will kbe described more fully hereinafter, illustrated in the drawing, and particularly pointed out in the claims.

In the drawing:

Fig. 1 is a perspective View of a razor embodying'my invention and showing the same in the position it will assume when being used as a conventional safety razor,

Fig. 2 is a similar view showing the head in such position as to permit of the device being used as a straight razor,

Fig. 3 is a fragmentary view showing in end elevation the head of the razor,

Fig. 4 is aview taken transversely through the razor head and a part of the handle,

Fig. 5 isa sectional view taken substantially on line 5-5 of Fig. 4, and

Fig. 6 is a view-taken longitudinally through the handle and head with the same in the position shown in Fig. 2.

Referring now more particularly to the drawing, the razor consists in a head indicated generally at 'l and a handle 8.

The head includes a body portion 9 from the lateral edges of which project cutting blades or edges IIJ. These blades are preferably formed integral with the head and are disposed in spaced parallel relation, so that each longitudinal edge is provided with a pair of complemental cutters. The material of which the head is made is such that the edges of the blades may be sharpened sufficiently keen for shaving purposes. Each pair of blades is provided with a guard indicated at l l, the said guards being arranged within the channels between the blades with their operative edges so disposed as to prevent the cutting edges coming in direct contact with a surface. The guard in each instance will preferably snugly t within the channel so as to be closely embraced by the blades, and it is desirable that the guards be capable of adjustment toward or away from the head proper. To this end, the inner faces of the blades and the outer or flat sides of the guards are provided with interengaging grooves and projections indicated at i2, such grooves and projections being disposed parallel with the cutting edges of the blades. By this arrangement it is obvious that the guards may be so positioned in their channels as to more or less expose their comb or operative edges, as may be desired. The ends of the channels are open so that the guards may be quickly and easily removed and adjusted.

The head has a stem I3 hinged or pivoted thereto as at Hl inY such manner as to permit of the head being reversed on the stem when desired. 'Ihe head has a slot l5 extending inwardly from one end thereof and medially of lthe head; the end of the stern I3 being pivoted in said slot so as to enable ythe head to move through an arc of substantially 180 with respect to the stem. l

The stem is slightly longer than the slot, and has its free end provided with a thread I6 to be engaged by an internal thread Il in the end of a handle I8, The thread l'l extends inwardly of the stern I3 sufciently to permit of binding engagement of the end of the handle I8 with the end of the head when the latter is disposed in a common plane with the stem, as shown in` Figs. 2 and 6. When so positioned, the device may be used as a straight razor with the benefit of the safety feature afforded by the guard ll, and it is obvious that any one of the four cutting edges may be brought into operative position by merely rotating the handle.

The base of the stem I3 is provided with a thread I9 to be engaged by the thread l'l of the handle when it is desired to use the device as a conventional hoe-type razor. In this latter use. the handle is turned upon the stem until the end of the handle firmly binds with the head. When it is desired to bring into operative position other cutting edges, it is but necessary to back 01T the handle until its end clears the end of the head, whereupon the latter may be swung through an arc of 180 to thus reverse itself upon the stem. The handle is then locked with the head in the manner described and the shaving operation may proceed.

With a razor constructed as described, it is apparent that I have provided means whereby any one of a plurality of cutting blades may be quickly and easily brought into operative position, whether the razor is to be used as a hoe-type or straight edge razor. When the head is in the position shown in Figs. 2 and 6, the several edges may be stropped selectively in much the same manner as the well known straight edge razor. By forming the blades of proper steel, keen edges may be maintained for an appreciable time by alternating the several blades in use. Should sharpening be required, it is simply necessary to remove the guards and apply a proper sharpening instrument to the interior as well as the exterior sides of the blades.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a safety razor, a head having spaced cutting edges integral therewith, and a guard between said edges.

2. In a safety razor, a head having integral spaced parallel cutting edges, and a guard between said edges.

3. In a safety razor, a head having spaced cutting edges integral with said head, and a guard between said edges and adjustable relatively thereto.

4. In a Safety razor, a head having a pair of spaced cutting edges integral with said head, a guard interposed between said edges, said guard adjustable relative to said edges.

5. In a safety razor, a head, a pair of cutting edges integral with said head and projecting therefrom, a guard arranged between said edges, said guard adjustable relative to said edges, and cooperating means on said guard and head for holding said guard in adjusted positions.

6. In a safety razor, a head, cutting blades arranged in spaced parallel relation on and integral with said head, and a guard interposed between and snugly embraced by said blades.

'7 In a safety razor, a head, cutting blades arranged in pairs on and integral with said head, a guard for each pair of blades, and each guard interposed between and snugly embraced by its respective blades.

8. In a safety razor, a head, a pair of cutting blades integral with said head and disposed parallel to each other, a guard interposed between said blades, and cooperating detents and recesses on said blades and guard whereby the latter is held in adjusted position.

9. In a safety razor, a head, a pair of cutting blades integral with said head and arranged parallel with each other, a guard between said blades, said guard having depressions in its sides in spaced relation laterally of the guard, and projections on said blades to engage in said depressions.

ll. In a safety razor, a head, a pair of cutting blades projecting from each side of said head, the blades of each pair arranged in spaced parallel relation and providing open ended channels, a guard for each channel, said guard having one edge projecting beyond the cutting edges of said blades, the inner faces of said blades provided with spaced parallel serrations, and similar serrations on opposed faces of said guard for interlocking engagement with the serrations of said blades.
